1 Claim. (Cl. 15-428) This invention relates to a bath brush, and itparticularly relates to a bath brush of the type having an internaisource of spray liquid.

The brush of the present invention provides a constant supply of wateror other liquid on the operational ends of the bristles, this liquidbeing permitted to flow through a large number of outlets in the brushadjacent the various bristles, and the flow being even anduninterrupted.

It has, heretofore, been known to provide liquid spray outlets from theinterior of a brush adjacent the bristles thereof. However, suchprevious types of liquid supply brushes have generally been subject tovarious disadvantages among the primary ones of which was the inadequatecirculation of the liquid within the brush. As a result, some of theoutlet openings would receive most of the liquid while others wouldreceive practically none. This led to an uneven treatment with the brushwherein some of the bristles were so soggy that their effectiveness wasalmost completely lost, while other bristles received so little liquidthat they were scratchy and irritating to the skin.

It is, therefore, one object of the present invention to provide a bathbrush having spray openings therein, wherein all the openings receive anequal supply of liquid from the internal liquid tank in the brush.

Another object of the present invention is to provide a bath brush ofthe above type, wherein clogging of the spray opening is prevented.

Another object of the present invention is to provide a bath brush ofthe above type wherein each bristle is so arranged relative to the sprayopening that each bristle is fully effective when wetted from the sprayopenings.

Other objects of the present invention are to provide an improved bathbrush, of the character described, that is easily and economicallyproduced, which is sturdy in construction, and which is highly eflicientin operation.

With the above and related objects in view, this invention consists inthe details of construction and combination of parts, as will be morefully understood from the following description, when read inconjunction with the accompanying drawing in which:

Fig. l is a general perspective view of a brush embodying the presentinvention.

Fig. 2 is a bottom view of the brush of Fig. 1, shown partly in sectionand partly in elevation.

Fig. 3 is a side elevational view of the brush of Figs. 1 and 2, partlybroken away, taken on line 3-3 of Fig. 2.

Referring now in greater detail to the drawing wherein similar referencecharacters refer to similar parts, there is shown a brush, generallydesignated 10, and comprising a head 12 and a hollow handle 14. The head12 comprises a top wall 16, of generally oval shape, provided with aperipheral skirt 18. The skirt 18 is provided, at the bottom rimthereof, with an inwardly extending flange 20 which is arranged tosupport the liquid tank 22.

The tank 22 comprises a spiral tube 24 which is rectangular incross-section, as best shown in Fig. 3, and which has an inlet end 26merging into a tube 28 set in the hollow handle portion. The inlet endof the tube 28 is provided with an annularly ribbed nipple 30 which isadapted to be coupled to a suitable flexible hose, or the like,connected to a source of liquid supply.

The tubing 24 and 28, as well as nipple 30, may be constructed of anydesirable material such as aluminum, certain of the vinyl resins, hardrubber, either natural or synthetic, or various other similar materials.The head 12 may be constructed of similar materials, and when made ofplastics, may be molded in position, and when made of metal, may haveits skirt flange 2t) and the tube portion spun or press fitted intoshape.

A handle grip 32, preferably constructed of plastic or hard rubber,surrounds the tube 28 and terminates in the nipple 30. A shoulder 34 isformed in the skirt portion 18 of the head 12, and the inner end of thehandle grip 32 closely bears against this shoulder 34.

On the bottom wall of the spiral tubing 24 there are provided a seriesof openings 36. Between each adjacent pair of these openings 36 isprovided a bristle tuft 38. It should be noted that the bristle tufts 38are so closely positioned to the openings 36 that the liquid sprayedtherefrom will impinge upon the working portions of the flared lowerends of the bristles adjacent thereto. Furthermore, the rectangularconfiguration of the tubing 24 provides a complete utilization of allavailable space; and this is particularly important in regard to thebottom walls of the tubing where no space is left between adjacent coilsof the spiral tubing.

The invention has been described above in relation to a constantlyrunning supply of liquid through the inlet nipple 30. However, it isalso possible to use the nipple 30 whereby as a filling nozzle which canbe plugged up after filling. The liquid will then be circulatedthrough-the tubing merely by manipulation of the brush. This type ofdevice is particularly advantageous where a liquid soap, oil or othersuch special fluid is used in the brush, and where a constant flow isneither necessary nor desirable.

Although this invention has been described in considerable detail, suchdescription is intended as being illustrative rather than limiting,since the invention may be variously embodied, and the scope of theinvention is to be determined as claimed.

Having thus set forth and disclosed the nature of this invention, whatis claimed is:

A bath brush comprising a head, a handle extending from said head, aliquid conduit in said head, said conduit being a spirally shaped tubehaving its internal end at the center portion of said head and itsexternal end integral with an inlet tube, said inlet tube extendinglongitudinally through said handle and terminating in an inlet coupling,said spirally shaped tube being rectangular in cross-section and beingprovided with closelyspaced, alternating bristle tufts and sprayopenings in the bottom wall thereof, said head comprising a topimperforate wall having a peripheral depending skirt, said skirt havingan inwardly extending flange at the lower rim thereof, said flange andskirt embracing said spirally shaped tube at its outer coil.
